AUTOMOBILE SANDER.

The present invention is concerned with the provision of a sander adapted to be associated with au automotive vehicle andl selectively controlledby theoperator of a car to-discharge sand'imnxediately in the path of the driving wheels.

One object of the invention is to provide va device of this character which may be very quickly and expeditiously mounted upon theV running board, or rather upon both running boards of the automobile, and consisting of a pair of sand hoppers with control valves selectively, simultaneously manually manipulated by a lever which is convenient to the drivers hand.

Further objects ot the invention are to provide a -sander of simple, practical construction which will be rugged, durable and eliicient in use, and which is well vsuited to the requirements of economical manufacture and convenient and expeditious attachment. With the above noted and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter setforth and pointed out in the claims. The invention may be more fully understood from the following description in connection with the accompanying drawings, whereinig. 1 is a view in side elevation showing the device of the present invention in operative position. the vehicle being indicated in dotted lines for the sake of clearness.

Fig. 2 is a top plan View of Fig. 1.

Fig. 3 is a vertical sectional detail through the bottom of one of the sand hoppers. the running board and the valve mechanism.

Fig. 4 is a sectional plan view of the valve mechanism taken on approximately the line 4-4 of Fig. 3.

In the drawings I have used the reference characters 10, 10 to designate a pair of sand hoppers mounted at the rear end of each of the running boards 11 of the car just in front of the rear mud-guards 12. Sand from the hoppers is delivered through the discharge spouts '13 which pass through the running board and discharge of sand from the spouts is controlled by av sliding valve plate 14 which Ishall more fully hereinafter describe. Both of the valve plates are connected by flexible devices 15 to an operating lever 16 arranged adjacent the drivers seat of the car. The lever coacts with an associated sector plate 17 'to lock Application ala November 27, 1926. v semina. 151,140.

the valve plates 14 in any desired position of adjustment, and when the lever is released, coiled contractile springs 18 automatically restore thevalve plates to the spout closing position of Fig. 3.

The valve plates are slidably mounted in guide plates 19, the latter being channelled as indicated at 20 to guide the movement of the plates 14. Nuts4 21 are rigidly mounted on the upper faces of the plates 19, these nuts encirclmg openings 22 in the plates 19 adapted to register with the bottoms of the discharge pipes 13.

Preferably the nuts 21 are first screwed on to the .threaded lower ends of the pipes 13 and the pipes 13 forced upwardly through prepared openings 23 in the running board. The pipes'also pass through openings in the bottom of the sand hopper, and their threaded upper ends are engaged by nuts 24 which serve to clamp the hopper against the upper face of the running board, and to draw the nuts 21 upwardly into firm engagement with the under face of the running board.

The hoppers themselves maybe of any desired shape and are preferably provided with removable covers 25 so thatthey may be conveniently lledalong the road if necessary.

The springs 18 connect the valve plates 14 with rearward extensions 26 of the plates 19, the springs normally holding the openings 27'in the plates 14 out of alignment with the openings] 22 in the plates 19.

The threaded connection of the nut 21and the plates 14 forwardly and partially orV completely register openings 27 with the opening 22. Thus a. temporary'or continuous heavy or light discharge of sand may be had from the hoppers, the sand falling immediately in the path of the rear wheels of the vehicle and effectively preventing y skidding on slippery surfaces.

Obviously various changes and alterations might be made in the general form and arrangement of parts described without departing from the invention. Hence I -do fnot wish to limit myself to the details set forth, but shall consider myself at liberty to make such changes and alterations as fairly fall Within the spirit and scope of the appended claims.

I claim:

l. The combination with an automobile including running boards, of sand hoppers mounted on the rear ends of the running boards, discharge pipes from the hoppers lext-ending through the ruiming boards and sliding control valves for the discharge pipes mounted under the running boards, the hoppers being clamped to the upper ends of the pipe and against the upper faces of the running boards.

2. The combination with an automobileincluding running boards, of sand hoppers mounted on the rear ends of the running boards, discharge pipes from the hoppers extending through the running boards and sliding control valves for the discharge pipes mounted under the running boards, and slide valve carriers clamped to the lower ends of the pipes. i

3. The combination with an automobile including running boards, of sand hoppers mounted on the rear ends of the running boards, discharge pipes from the hoppers extending through the running boards and sliding control valves for the discharge pipes mounted under the running boards, nuts screwed on to the opposite ends of the discharge pipes and retaining the valves and the hoppers.

4. The combination with an automobile including running boardsjot sand hoppers mounted on the rear ends of the running boards, discharge pipes from the hoppers extending through the running boards and sliding control valves for the discharge pes mounted under the running boards, ever operated exible devices associated with the slide valves for selectively manually simultaneously partially or completely openingV them.

5. The combination with an automobile including runningboards. of sand hopper-s mounted on the rear ends of the running boards, discharge pipes from the hoppers extending through the running boards and .sliding control valves for the discharge pipes mounted under the running boards, lever operated fiexible devices associated with `the slide valves for selectively manually simultaneously partially or completely opening them, and springs normally holding the valves closed.

6. A sand hopper adapted to be mounted on the running' board of an automobile and including a discharge pipe adapted to project downwardly through the running board, a channelled' plate having an opening therein and including a nut like boss adapted to be screwed on to the lower end of the discharge pipe, a slide valve mounted for movement in the plate.

Y7. A sand hopper adapted to be mounted on the running board of an automobile and including a discharge pipe adapted to project downwardly through the running board,

a channelled plate having an opening therein and including a nut like boss adapted to be screwed on to the lowerend `of the discharge pipe, a slide valve mounted for movement in the plate, and a valve-closing spring anchored to an extension of the channelled plate.
